Church, who came off the bench to score twice in the 3-0 win over West Ham at the weekend, is thought to be frustrated at being unable to nail down a regular starting spot in Brian McDermott's starting XI this season.

The Wales international has made 12 starts in the Championship this season, but has only played the full 90 minutes twice in those dozen games.

The 22-year-old is believed to be keen on getting more playing time under his belt as he looks to push his international claims with Wales.

The news has alerted a number of clubs to Church's possible availability with the talented striker having no shortage of admirers in the Premier League and Championship.
